Frequently Asked Questions

Is the system compatible with my existing solar inverter?

Our batteries offer high compatibility with various solar inverters using RS485, CAN, or RS232 protocols, supported by most major brands like SMA, Growatt, Deye, and Victron.

What is the expected lifespan of these batteries?

Lithium iron phosphate (LFP) batteries typically offer 6,000-8,000 charge cycles, which is equivalent to 10-15 years of daily use depending on maintenance and temperature.

What safety features are included?

The system includes a comprehensive Battery Management System (BMS) with overcharge, over-discharge, short-circuit, overcurrent protection, and continuous temperature monitoring.

How can I monitor the performance of my battery?

We provide a cloud-based monitoring platform via mobile app and web. You can track real-time performance, charging status, and overall battery health.

What are the main application scenarios?

Ideal for integrated solar-storage-charging systems, peak-valley electricity arbitrage, emergency backup power, and usage in low-temperature environments.

Does installation require professional expertise?

Yes, installing these energy storage batteries requires specialized knowledge. We recommend hiring certified professionals to ensure safe integration with your electrical system.
